Colonic Cancer and Acromegaly

Acromegaly results in a significantly increased morbidity and mortality due to cardiovascular and respiratory complications as well as malignancies arising mainly from the colon. Furthermore, an increased lifetime risk of malignant transformation of pre-malignant colonic lesions relates to a worse overall prognosis from colorectal cancer, which is currently considered a major disease related complication. In this review we provide some insight into colonic changes in this condition, summarise current knowledge and evidence on the use of colonoscopic screening in patients with acromegaly, and suggest a recommended screening protocol.

Health-Related Complications of Acromegaly—Risk of Malignant Neoplasms Marek Ruchala*† and Kosma Wolinski† Department of Endocrinology, Metabolism and Internal Medicine, Poznan University of Medical Sciences, Poznań, Poland The issue of increased risk of benign and malignant neoplasms in patients with acromegaly remains the topic of debate from many years and was addressed by numerous studies. Many of them have shown increase in the cancer incidence. Among particular types of malignancies, thyroid, colorectal, and breast cancer are most commonly indicated as associated with acromegaly. Single ...

Authors: Hancerliogullari O, Senocak R, Kaymak S, Lapsekili E, Sinan H Abstract Acromegaly is a chronic endocrine disease, typically caused by a pituitary adenoma leading to increased circulating GH levels and increased IGF-I secretion by peripheral tissues. Gastrointestinal diseases related acromegaly such as colon cancers, adenomatous polyps, and dolichocolon are much less known. We aimed to present a case of complete colonic volvulus in a patient with acromegaly. A 60-year-old male patient presented with the complaints of inability to pass gas or stool, worsening distension, and pain for one week. The clinical e...

CONCLUSIONS: Benign neoplasms were found in majority of patients with acromegaly (71.6%) most notably: nodular goiter and colon polyps; malignant lesions were rare (4.5%). Only every fifth patient suffered from no neoplastic proliferations. No correlations between the studied parameters and the incidence of neoplasms were found, most likely due to the small number of patients. This is the reason for proposing the creating of the first national register of incidences of neoplasms among acromegalic patients. PMID: 30260174 [PubMed - in process]

In conclusion, although cecal intubation during colonoscopy was successful in all participants, it required a longer time in patients with acromegaly. Our results underscore the importance of and certain technical difficulties involved in colonoscopy procedures in patients with acromegaly, especially in older patients.

AbstractPurposeAcromegaly is a disease associated with an increased risk for several kinds of neoplasms including colon and thyroid cancer. Although the association between acromegaly and pancreatic neoplasms has not been elucidated, it has recently been reported thatGNAS gene mutations were found in 58% of intraductal papillary mucinous neoplasms (IPMNs), which are representative pancreatic cystic lesions, suggesting a link between IPMNs and acromegaly. To assess the prevalence of pancreatic cystic lesions in patients with acromegaly, we performed a retrospective cross-sectional single institute study.MethodsThirty consec...

ConclusionsMalignant neoplasms are significantly more common in patients with acromegaly. Particularly, risk of thyroid cancer was increased over fivefold. Systematic screening for neoplastic diseases should be important part of follow-up in these patients. Further case –control studies are strongly indicated to evaluate which neoplasms are more common in acromegalic patients and what is the exact risk of malignancy.

CONCLUSIONS: This study suggests that patients with acromegaly have an increased risk of thyroid cancer and therefore they should undergo regular screening with hormonal and ultrasound evaluation of the thyroid and FNAB when required. PMID: 27685924 [PubMed - as supplied by publisher]

ConclusionThyroid micro-carcinomas are probably over-diagnosed among acromegalic patients. In regard to colon cancer, there is no sufficient data to suggest that colon cancer risk is higher in acromegaly compared to the general population.

Objective It is unclear whether mortality still is increased in acromegaly and whether there are gender-related differences. We dynamically assessed outcome during long-term follow-up in our nationwide cohort. Patients and methods We studied standardized mortality ratios (SMRs) relative to the general population and causes of death in acromegaly (n=333) compared with age- and gender-matched controls (n=4995). Results During 20 (0–33) years follow-up, 113 (34%) patients (n=333, 52% women) and 1334 (27%) controls (n=4995) died (P=0.004). SMR (1.9, 95% CI: 1.53–2.34, P
